Disadvantages of the Mazda L3-VDT engine
- This engine does not like bad fuel, up to the destruction of the piston group;
- The resource of the timing chain and phase shifter sometimes does not even reach 100 thousand kilometers;
- The turbine can quickly fail due to coking of oil in its supply pipes;
- The fuel pressure sensor in the high pressure fuel pump often leaks, which is simply fraught with fire;
- The engine is prone to oil consumption, if you miss the oil level, it will turn the liners.
